Diff Tail Trim, my photo of the GR1 cockpit, I wondered if it was a A'ish as when I was on them it didn't originally have the small panel Chaff / Flare panel under the Camera though they were fitted later during my tour, and I cannot remember the big lump on the top right of the hud on the upper coaming with the black yellow button.
We did have the underwing sidewinders though on the inboard pylons I think.. for a period.
